Magnetic Tuning of Upconversion Luminescence in Lanthanide-Doped Bifunctional Nanocrystals

摘要

Optical-magnetic (OM) bifunctional materials are of great interest for developing advanced multifunctional devices.'1"41 Conventional OM bifunctional materials are composites that are produced by coupling optical materials with magnetic ones. It is very difficult to realize an interaction between the optical and magnetic properties (e.g., tuning the optical properties using a magnetic field) in these conventional OM materials because of the separation of the optical and magnetic phases. On the other hand, producing materials with OM interactions would be valuable for developing advanced OM devices for high-accuracy communications, aircraft guidance, and magnetic field detection.
